1. A nurse has been ordered to administer Morphine to a patient. Which of the following effects is unrelated to Morphine's effects on the patient?
- A. Depressed function of the CNS
- B. Increased blood flow
- C. Decreased venous capacity
- D. Pain relief
Correct answer: C
Rationale: Morphine is a narcotic analgesic that acts centrally to relieve pain by binding to opioid receptors in the CNS, leading to the depressed function of the CNS. Morphine also causes peripheral vasodilation, which can lead to increased blood flow. However, morphine causes venous dilation and increased venous capacity rather than decreased venous capacity. Therefore, the effect of 'Decreased venous capacity' is unrelated to Morphine's effects. Pain relief is a well-known effect of Morphine, as it acts on the CNS to alter the perception of pain.
2. A woman is in the active phase of labor. An external monitor has been applied, and a fetal heart deceleration of uniform shape is observed, beginning just as the contraction is underway and returning to the baseline at the end of the contraction. Which of the following nursing actions is most appropriate?
- A. Administer O2 if necessary.
- B. Turn the client on her left side.
- C. Notify the physician.
- D. No action is necessary.
Correct answer: D
Rationale: The correct answer is 'No action is necessary.' In this scenario, the fetal heart deceleration of uniform shape observed is an early deceleration resulting from head compression. Early decelerations are benign and typically do not require any intervention as they mirror the contraction pattern. It is essential to closely observe both the mother and the baby. Administering O2 (Choice A) is not necessary as early decelerations do not indicate fetal distress. Turning the client on her left side (Choice B) is not required for early decelerations. Notifying the physician (Choice C) is not needed for this type of deceleration, as it is a normal response to head compression during labor.
3. After applying oxygen using bi-nasal prongs to a client who is having chest pain, the nurse should implement which intervention?
- A. Have the client take slow deep breaths in through their mouth and out through their nose.
- B. Post signs indicating that oxygen is in use on the client's door and in their room
- C. Apply Vaseline petroleum to both nares and 2 by 2 gauze around the oxygen tubing at the client's ears
- D. Encourage the client to hyperextend the neck, take a few deep breaths and cough.
Correct answer: A
Rationale: After applying oxygen using bi-nasal prongs to a client with chest pain, it is essential for the nurse to post signs indicating that oxygen is in use on the client's door and in their room. This safety precaution alerts healthcare providers and visitors that the client is receiving oxygen therapy, reducing the risk of accidents or misunderstandings. Choice A is incorrect because instructing the client to take slow deep breaths is not the appropriate intervention after applying oxygen. Choice C suggests applying Vaseline and gauze, which is unnecessary and not a standard practice. Choice D advising the client to hyperextend the neck, take deep breaths, and cough is not indicated after applying oxygen therapy and could potentially be harmful.
4. When preparing a client for platelet pheresis in the blood bank, which information is most significant to obtain during the history assessment?
- A. Allergies to shellfish
- B. Date of last platelet donation
- C. Time of last oral intake
- D. Blood type
Correct answer: B
Rationale: The most significant information to gather when a client is scheduled for platelet pheresis is the date of their last platelet donation. Platelet donors can typically have their platelets apheresed as frequently as every 14 days. Knowing the date of the last donation helps ensure the client is eligible for the procedure without risking any adverse effects from frequent donations. Allergies to shellfish may be important for other procedures where anticoagulants containing heparin are used, but it is not directly related to platelet pheresis. The time of the last oral intake is more crucial for procedures requiring sedation or anesthesia. Blood type is significant for blood transfusions but is not the primary concern for platelet pheresis.
5. A client has been receiving cyanocobalamin (B12) injections for the past 6 weeks. Which laboratory finding indicates that the medication is having the desired effect?
- A. Neutrophil count of 60%
- B. Basophil count of 0.5%
- C. Monocyte count of 2%
- D. Reticulocyte count of 1%
Correct answer: D
Rationale: Cyanocobalamin is a B12 medication used for pernicious anemia. A reticulocyte count of 1% indicates the desired effect of the medication, as reticulocytes are immature red blood cells that increase in response to B12 therapy, improving anemia. Neutrophils, basophils, and monocytes are white blood cells and are not directly influenced by B12 injections, making them incorrect choices.
